Looks like an oversized valve to me, as I compare it to mine that is apart. I have those silly V-twin valves with the dip in the top. Anyone know how these will affect a street motor? I am hard on equipment, but don't do a lot of top speed work. I have a set of KHK cams I would like to put in at some point after I have them rebuilt, and will likely hunt up another set of valves for them then. These came in Sifton packages from V-twin. They ran OK on the last go around, though the engines lower end was so loose it eat through the rings very quickly, and the carbon messed up the pistons badly.

100inch, what is the base number anyway?

Best Regards,

Mike, if the base # is -52, they're K, -54 KH. If it's K model, looks like some one put KH intake valves in it and dressed up the relief a bit. Is the intake passage cleaned up and smoothed also? G
